Exactly. This is why for all Perl scripts I'm going to distrubute on other systems I use ExtUtils::MakeMaker which does such patching automatically.

Either that's a recent feature (and therefore not portable), or hasn't been documented.

Where did you find out about this?

I think it was there at least since 5.005. There is some mentions of this feature in ExtUtils::MM_Unix (search for fixin) but it seems it is not documented anywhere properly.

From personal experience. I just noticed that ExtUtils::MakeMaker always replaces my shebang with something else :) For example on my Linux system it replaces existing shebang with

#!/usr/bin/perl -w

eval 'exec /usr/bin/perl -w -S $0 ${1+"$@"}'
    if 0; # not running under some shell

On Win32 I noticed that ExtUtils::MakeMaker does another magic. It creates .bat file which wraps perl script and adds .pl extenstion to perl script when doing its installation. I found that at least on Unix, Unix-like systems and on Win32 systems ExtUtils::MakeMaker does the right thing.
